Matter In Ecology

Different levels of organization of matter in ecology

INTRODUCTION.

Ecology is related to the study of interaction between living components on earth which is also known as biotic factor with non-living component on earth and their environment. Every living thing on earth interacts with each other together with non-living environment with some source of energy in order to complete the ecosystem. The definition of ecosystem is about the same to the definition of ecology.

Ecosystem is defined as the interaction between biotic and abiotic components in a habitat. Biotic component composed of living organisms in an ecosystem within the biosphere like birds, animals, plants, fungi which is able to mate with their species to produce more number

They are organisms, population, community, ecosystem and also biosphere. Ecologist study the atomic level of organization matter to the biosphere level of organization matter. Primarily, an organism is developed from an atom. The atom then combined to form molecule and the molecule develops into cells forming tissues, organ and organisms. The figure below shows the different levels of organization of matter in ecology:

A complete ecosystem must have three different living components which are producer, consumer and also decomposer. They involve in the feeding level that is also known as trophic level in the food web. The figure below shows the complete ecosystem interaction between the animals and plants in the environment: In the ecosystem, producer usually is the plants on the earth. Plants which also known as autotrophs can make their own foods by undergo the photosynthesis process. Photosynthesis process requires sunlight as the source of energy. Besides sunlight, carbon dioxide and also water are needed to complete the photosynthesis process and to get the products that consist of glucose and

The population of human continually increases. As the number of human population get increase, the more usage of technology occurred. The usages of technology lead to the disruptions of other natural populations. This may cause the number of population growth and declination are not under controlled

The next reason that causes the declination of population is because of pollution. Pollutions occur because of the release of pollutant into the environment like into the air or water whether intentionally or unintentionally. Like example, the exceed usage of pesticide, fertilizers and herbicides lead to pollution of the environment. When it is raining, the runoff from the agricultural pesticides, fertilizers and herbicides may impact the nearby lake. This may cause the occurrence of eutrophication in the lake which may lead to the declination of fish population in the lake.

Next is the usage of pesticides and competition among the individuals in the population for limited sources like foods and shelters. The removal of competitor species shall lead to the explosion of other species that is more resistant to competition. For example, the usage of pesticide sprays on the paddy fields may cause the secondary pest outbreak which is more resistance to the pesticide because the once less tolerant species competitors were
